Abstract: PURPOSE: To prevent a tailing phenomenon of toner by providing a means for applying bias voltage of the same polarity as that of charges of toner to an elastic body of a fixing roller containing a conductive member to make a speci fied value of an electric current flow to a transfer material. CONSTITUTION: Methyl phenyl base silicone oil which is a conductive member is applied to an elastic body of a fixing roller 1 by an application roller 11. The temperature of the fixing roller 1 is kept above 140 deg.C, for example 160 deg.C-180 deg.C, whereby the impregnating ability of oil is further increased, and the conductivity of oil itself is increased. Bias voltage of the same polarity as that of charges of toner is applied to the core bar 2 of the fixing roller 1 by a power supply 20 to make an electric current about 0.1μA-10μA flow from the fixing roller 1 to a pressure roller 4. The voltage of the power supply 20 is controlled in such a manner that an electric current about 0.1μA-5.0μA is made to flow from the fixing roller 1 to a transfer material P.  Thus, toner is electrostatically held on the transfer material so as to prevent the occurrence of a tailing phenomenon.

IPC: H04B10/58
Filed: 1984-06-25
Abstract: PURPOSE:To attain circuit integration, miniaturization and to transmit a picture and sound with high quality by utilizing sufficiently the advantage of digital multiplex. CONSTITUTION:Two kinds of sound signals 12, 13 are subjected to PCM coding by using a PCM encoder 11 at first, then subjected to digital multiplex with a data signal 14 and the 1st carrier in 5MHz-15MHz, for example, is subjected to angular modulation by using a signal applied with digital multiplex with a modulator 15. Then the signal subjected to angular modulation and a video signal 16 are subjected to frequency division multiplex at a synthesizer 17 and the 2nd carrier of 10MHz-100MHz is modulated by using a signal subjected to frequency division multiplex by a modulator 18. Since the multiplexed signal calls for linearity and an electrooptic conversion is nonlinear, the modulation has only to be executed by a PFM in advance. Thus, the linearity is kept, the S/N is improved and long range transmission is attained.

Title: Feeding device in xy direction
Inventor: SUZUKI RYOICHI
IPC: B23Q1/00
Filed: 1988-05-26
Abstract: PURPOSE:To elongate storoke length and to improve a positioning accuracy by eliminating play by arranging a Y direction driving shaft and X direction driving shaft so as to contact each other by rolling by intersecting each other at right angles and giving pressurization to each driving shaft. CONSTITUTION:The rotation of the driving shaft 21 for an X direction functions as the feeding roller roll-contacting with the driving shaft 11 for Y direction and is made to be moved in the axial direction of the driving shaft 11 with it as a feeding bar. However, the driving shaft 11 is not moved in the axial direction, so an X table 3 is moved in the X direction by reaction and the Y table 5 located on the X table 3 is also moved in the X direction. Similarly a Y table 5 is moved in Y direction by the rotation of the Y direction driving shaft 11. The Y table 5 is moved in the selected direction by the selection of driving motors 7, 17 and moved in the direction composed by the simultaneous driving. The stroke can therefore be elongateed because of the feeding by the roll contact being utilized and the positioning accuracy is improved because of play being eliminated on the driving shafts 11, 21 by pressurization.
